“…However, findings in flies and moths regarding the regulative role of CCAP are not fully consistent and call for further investigation (Zitnan et al, 2007). Bestman and Booker observed that CCAP generated increased motility and in many cases peristalsis in Manduca during the larval-larval moults (Bestman and Booker, 2006). They suggest that the role of this modulation is to control the timing of moulting fluid ingestion.…”

SummaryA possible role of the insect stomatogastric nervous system (STNS) in ecdysis was first implied in early studies reporting on internal air pressure build-up in the digestive tract and air swallowing during ecdysis. The frontal ganglion, a major component of the insect STNS, was suggested to play an important part in this behaviour. Recent neurophysiological studies have confirmed the critical role of the STNS in the successful completion of both larval and adult moults in insects. In aquatic arthropods, though much less studied, the STNS plays an equally important and probably very similar role in water swallowing. Water uptake is instrumental in splitting the crustacean cuticle and allowing successful ecdysis. Current data are presented in a comparative view that contributes to our understanding of the role of the STNS in arthropod behaviour. It also sheds light on the question of homology of the STNS among the different arthropod groups. New insights into the neurohormonal control of ecdysis, related to the STNS in both insects and crustaceans, are also presented and comparatively discussed.
